ATTACBIMENT FOR STEAM-SIIOVEL SCOQPS.

Specification of Letters Patent.

Patented 32m. 7, 1908.

To all whom it may concern:

Be it known that 1, JAMES W.- TURNER, a citizen of theUnited States,residing at Reelsville, in-the county of Putnam and State of Indiana,have invented certain new and useful Iln rovements in Attachments forSteam- Shove Scoops; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame- My invention relates to attachments for shovels, and moreparticularly to that class known as steam shovels, and my object is toprovide means for re-inforcing the digging tooth employed in connectionwith this form of'shovel.

A further object is to provide means for renewing portions of the tooth,so that when the same ecomes Worn, a new tooth may be attached to theshovel, and a still further object is to provide means for securing thetooth to the shovel.

Otherpbj'ects and advantages will be hereinafter referred to' and moreparticularly pointed out in the claims.

In the accompanying drawings, which are madea part of this application,Figure 1 is a top plan view of a portion of a shovel, showing myimproved finger attached thereto. Fig. 2 is a sectional view as seen online 22 Fig. 1. Fig. 3 is a sectional view thereof,- as

seenon line 3-3 Fig. 2, and, Fig. 4 is an elevation of my deviceemployed in securing the housing for the finger to the shovel.

.Referring to the drawings in which similar reference numerals designatecorresponding parts throughout the several views, 1 indi cates a scoopor shovel such as is commonly used in connection with steam excavators,and in use, the scoop is forced into en agement with the earth until thescoop is filled, and in order to readily loosen the earth, a pluralityof fingers are employed, which ex tend beyond the engaging end of thescoop,

and it has been found that the fingers as now commonly employed 'cannotbe properly braced, and to this end I provide my 'imroved form offinger,'which consists'of a body portion 2, to the outer end of which isremovably secured a head 3, said head being tapered at its free end,while the opposite end thereof is provided with ears 4 and 5, whichextend overthe reduced end 6 of the the bores 14 an Application filedhlay 16.1907.

body 2, and is rernovably secured thereto by directing a bolt.7vertically through the ears and through the end 6.

The forward end of the scoop I is provided with a lip 8, whichextendssubstantiallyhalf its width beyond the edge of the scoop, and l,

is secured thereto by means ofrivets .9, or the like, said lip beingsecured to the upper surface of the $000 and the projecting por tionthereof exten s into'a slot 10, f0rrned in the forward end of the bodyportion 2, and

it'will be seen that when the lip'is thussecured in the slots, the lipWille held perfectl rigid and prevented from bending or brea ing. H

The rear end of the bod 2 is extended a distance over the surface 0 thescoop, and is reduced in size to form a shank 11, said shank. beingadapted to enter a socket 12, which is in turnsecured to the floor of.the scoopin any preferred'manner, as by directing rivets 13 through thescoo and floor of thesoclse't, and in order to en'ab e me to secure therivets in position through the socket and scoop, I

provide a plurality of bores 14, in the upper wall of the socket 12,through which the rivets are passed and seated in the openings in thescoop and lower wall of the socket, and after therivets are thus seated,the lower ends thereof are upset in the usual manner to form heads onthe lower ends of the rivets, and to readil and positively hold therivets in position w ile being u set, I provide a bar 15, which is adated to e inserted through into enga ement with tea headed ends of therivets, the engaging end of the bar 15 having a concave depression 16therein to receive the heads of the rivets, and revent the bar fromslippin and by providing. the bar'of sufficient weig .t, blows may bedelivered to the outer end of the rivets without dis lacing the bar fromthe inner ends thereo I In order to allow the shank 1.1 to freely en- I--n1 position on the S000 the fingers will cause the metal forming theWhat I claim is:

scoop, to bend, and to this end, therefore,

1. The combination with a scoop ofv the Iprovide the socket 12, wherebyI am en- 5 class described of-a finger,- said finger. being ab ed todispense with the fillers, and it will be seen that the fingers can bequickly placed when the finger becomes broken orot erwise destroyed,

I While in" the old form of finger, itis necessary to rivet the same inposition, thereby necessitating a great loss of time and expense.

In securing the. fingers in position, the sockets are first secured tothe scoop, after which the shank 11 is inserted inthe socket and a bolt18 extended-through the body portion 2 and outer edge on the lip 8,while a bolt 19 extends through the body portion,

lip and front edge of the scoop, said bolts being providedwith lockingnuts 20, said nuts being at'the upper endsof the bolts, and to preventthe nuts from obstructing the passage of the earth, the upper surface ofthe ody portion, surrounding the openings to receive the bolts, iscountersunk, so that the u per ends of the bolts and the upper faces ofthe nuts thereon, will be flush with the face of the body portion. Inorder to retain the bar 15in readiness to be used and also to preventthe same from becoming lost,

secure to any convenient part of the shovel, a keeper 21, one end ofwhich is adapted to be secured to the shovel, while the opposite endthereof is provided with a depending end 22, said em having a notch 23therein,

- which is adapted to receive the links of a chain 24, one end of thechain being secured to the depending end 22, while the opposite end ofthe chain is secured to the bar 15, and after the bar has been used,that portion ofthe chain adjacent to the bar is placed in the.

notch 23, so that the bar will be suspended adjacent to the keeper. r
